About this Add-on
This extension allows you to set custom new tab page, instead of default about:blank.
The setting is located in the options window of this add-on. It's also added to the browser preferences, next to the startup page setting.
You can make an HTML file with a list of your favorite websites, and set it as a new tab page to have easy access similarly to bookmarks.
The Custom New Tab extension is a restartless extension which does everything this extension does, plus a little more. I am looking into options of updating you all to that extension with a next version. --12/07/2014
